Red plum is a kind of plum blossom, a small tree and sparse shrub of the genus Apricot in the Rosaceae family, 4-10 meters high. It has a cultivation history of more than 3,000 years in China. Plum blossom is the first of the top ten famous flowers in China. It is listed as the Four Gentlemen together with orchid, bamboo and chrysanthemum. It is also known as the "Three Friends of Suihan" together with pine and bamboo. Red plums are mainly cultivated in gardens, green spaces, gardens, and scenic spots. They are one of people's favorite flowers and trees. Most families in our village have red plums planted in their yards. The flowering period is in the cold winter season. The time when snowflakes fall every winter is the season when red plum blossoms bloom. You can enjoy both plum blossoms and snowflakes.

Red plums are native to the south of the Yangtze River in my country, and the centers of cultivation are Chengdu, Hangzhou and Wuhan. Plum blossoms like to grow in a warm and humid climate. They can grow well under sufficient light and good ventilation. They are not strict with the soil and are resistant to barrenness, cold and water accumulation. It is suitable to grow on moist soil with loose, fertile topsoil, good drainage and slightly sticky subsoil. Red plums love warmth and plenty of light. In addition to being able to withstand low temperatures of -25°C, it is also resistant to high temperatures and can grow at 40°C. It grows best in areas with annual average temperatures of 16-23°C. It is very sensitive to temperature and can still bloom when the temperature is below 0℃ in early spring.

Pruning of red plums: The flower buds of red plums are formed on the new branches of the year. In order to make the red plums bloom more, you can use pruning method to make the red plums have more branches. This is very important. Before flowering, Sparse buds.

Red plums have relatively strong germination ability and tend to branch out. If you do not pay attention to pruning and shaping, the red plum tree will be disorganized, with too many leggy branches and too strong branches, and very few flower buds will be formed on the branches that grow in the current year. , Therefore, it is very important to prune and shape red plums in time. Pruning is usually done after the flowers fade, and strong or young trees should be pruned lightly. Weak trees and old stumps need to be pruned again. In terms of branches, strong branches should be pruned lightly and weak branches should be pruned heavily. Insect-infected branches, leggy branches, delicate branches, overlapping branches, dead branches, etc. need to be pruned at any time. Properly prune the main branches and side branches that have bloomed, and then leave 2-3 short cuts of the side branches on the main branch after the buds. After entering autumn, shorten the short branches with flower buds appropriately, and cut off the upper parts of the long branches with leaf buds, leaving 5-6 leaf buds. Generally, 3-5 main branches are left per plant, with alternating lengths, heights, and density.

Maintenance of red plums:

Red plums can be used as potted plants. When potted, choose plants that are close to flowering in the spring before the new leaves have unfolded and pot them with soil. Choose loose soil. Use fertile sandy loam as the potting soil, and add some decomposed cake fertilizer. After potting, water it twice in succession, and then place it in a sunny place for cultivation.

Red plums are afraid of waterlogging. Too much water will damage the roots and cause leaf fall, which will affect the opening of buds. If there is too much water in spring, it will easily lead to leggy growth and fewer flower buds. In autumn, when there is too much water, it is easy for a lot of leaves to fall. Too much water in winter can easily cause root rot. Drainage ditches must be dug for red plum trees planted on the ground, and standing water must be removed after rain. Potted plants are usually watered once a day in the afternoon in summer, and the accumulated water is drained in time on rainy days. Watering should be reduced in autumn and during the flowering and leaf unfolding periods. The principle of watering is to see dry and wet. If the green leaves fall off, it means there is too little water. If the leaves turn yellow and fall off, it means there is too much water.

For fertilizing red plums, in addition to applying sufficient base fertilizer when potting and changing pots in spring, a familiar thin liquid fertilizer should be applied once a month during the summer growth period. When new shoots stop growing and flower buds differentiate, quick-acting fertilizer should be applied to promote flower bud differentiation. During the bud-pregnancy period in autumn, it is necessary to stop applying nitrogen fertilizer and add a small amount of quick-acting phosphorus fertilizer to control the growth of red plum plants and promote flower bud differentiation. Also apply budding fertilizer and shoot-promoting fertilizer after flowering.
